Holder for conveyance of cylindrical body

Abstract

A holder for conveyance of a cylindrical body includes a tubular portion having a hollow portion in which a cylindrical body is housed, and a protrusion having a base end connected to an inner wall surface of the tubular portion and a distal end formed as a free end. The protrusion has elasticity and flexibility, and the protrusion is disposed on an inner diameter side of an outer circumferential surface of the cylindrical body at an expected housing position such that a side surface of the distal end of the protrusion is allowed to come into contact with the outer circumferential surface while the protrusion is warped to an outer diameter side of the hollow portion.

The invention claimed is: 
     
       1. A holder for conveyance, comprising:
 a tubular portion having a hollow portion in which a cylindrical body is housed; and 
 a protrusion having a base end connected to an inner wall surface of the tubular portion and a distal end formed as a free end, 
 wherein the distal end includes a pair of opposed, first and second ends along a direction in which the protrusion protrudes, the first end being fixed to the inner wall surface via the base end, and the second end being the free end which is free from fixation to the inner wall surface, 
 wherein 
 the protrusion has elasticity and flexibility, and 
 the protrusion is disposed on an inner diameter side of an outer circumferential surface of the cylindrical body at an expected housing position such that a side surface of the distal end of the protrusion is allowed to come into contact with the outer circumferential surface while the protrusion is warped to an outer diameter side of the hollow portion. 
 
     
     
       2. The holder for conveyance according to  claim 1 , wherein the protrusion is formed in a strip shape along an axial direction of the tubular portion. 
     
     
       3. The holder for conveyance according to  claim 1 , wherein
 the hollow portion is a substantially columnar shape, and 
 the expected housing position of the cylindrical body is located on a concentric circle of the hollow portion. 
 
     
     
       4. The holder for conveyance according to  claim 1 , wherein the protrusion has a bent portion. 
     
     
       5. The holder for conveyance according to  claim 1 , wherein a plurality of the protrusions are formed in a plurality of positions on the inner wall surface in a circumferential direction of the tubular portion. 
     
     
       6. The holder for conveyance according to  claim 5 , wherein the protrusions formed in adjacent positions in the circumferential direction of the tubular portion have bent portions bent in directions opposite to each other. 
     
     
       7. The holder for conveyance according to  claim 1 , wherein the protrusion is formed of a resin material having elasticity.
